2-1 Sled Offset Adjustment
1. Connect the probe of oscilloscope to pin 1 (SLCNT) of P205 on
CORE PCB, and the probe earth to pin 2 (SL18V).
2. Set the oscilloscope's voltage range to DC100mV, and the time
calibration to 10mS.
3. Adjust potentiometer R232 for a potential difference of 0V
between pins 1 and 2.
2-2 Sled Gain Adjustment
1. Connect the probe of oscilloscope to pin 3 (H1OUT) of P205 on
CORE PCB, and the probe earth to pin 2 (SL18V).
2. Set the oscilloscope's voltage range to AC200mV, and the time
calibration to 10mS.
3. Press the DF range button on RC-668 (P/No. E00380000A), a
remote controller for VRDS-8, to activate the sled, and adjust
potentiometer R235 for a sine wave output of 1Vp-p at pin 3.
Pressing the DF range button again beings the unit back to the
normal mode.

Cautions about Disassembly and Mounting
●After joining CLAMPER MAGNET 1and DISC CLAMPER 2
with adhesive, ThreeBond 1359D, harden forced out surplus
adhesive with UV irradiation.
●Avoid applying a strong pushing force to the PU BASE ASSY
when removing/installing the PUSH SW 9.
●When fastening the SA SLED MOT ASSY a, push it against
the locating pin.
●Fasten the STOPPER BELT PLATE @so that there is a
clearance of 1 mm between it and PULLEY (B) PLATE ..
●For the MOTOR HOUSING ASSY, first fully tighten down the
screws on the left end viewed from the front.
●Avoid disassembling parts that are not "exploded" in the
diagram (such as PU BASE ASSY, MOTOR HOUSING ASSY).
Dedicated tools are required to assemble them. When those
parts are needed to replace, the MECH UNIT itself should be
replaced.
